Answer:

x = 0

y = -12

Step-by-step explanation:

Plug in what y is equal to into the second equation

-3(x - 12) = 2x + 36

Distribute the -3

-3x + 36 = 2x + 36

-36 -36

-3x = 2x

They cannot be equal so x = 0

Plug in 0 into the y equation

y = 0 - 12

y = -12

Answer:

$\displaystyle y = -\frac{6}{7}x + 5\frac{5}{7}$

Step-by-step explanation:

First, find the <em>rate of change</em> [<em>slope</em>]:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-10 + 4}{5 + 2} = -\frac{6}{7}$

Now plug these coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:

4 = −6⁄7[2] + b

−1 5⁄7

$\displaystyle 5\frac{5}{7} = b \\ \\ y = -\frac{6}{7}x + 5\frac{5}{7}$

_______________________________________________

10 = −6⁄7[−5] + b

4 2⁄7

$\displaystyle 5\frac{5}{7} = b \\ \\ y = -\frac{6}{7}x + 5\frac{5}{7}$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.
